% Transformation matrix from ecliptic to Earth equatorial planes. This is a single rotation about the x-axis. If the jd is not input it will use the mean obliquity for J2000.0. Since version 1. -------------------------------------------------------------------------- Form: c = CEcl2Eq( jD ) -------------------------------------------------------------------------- ------ Inputs ------ jD (1,1) Julian date ------- Outputs ------- c (3,3) Transformation matrix from the ecliptic plane to the equatorial plane -------------------------------------------------------------------------- References: Montenbruck, O., T.Pfleger, Astronomy on the Personal Computer, Springer-Verlag, Berlin, 1991, p. 15. --------------------------------------------------------------------------
